Save-and-return field test · September 27, 2026

Best incremental games for short browser check-ins: can you save and come back?

In a same-browser refresh test, Cookie Clicker, Kittens Game and Antimatter Dimensions all kept the small amount of progress we made. Kittens Game and Antimatter Dimensions also let us use an explicit Save control before refreshing. This answers a narrow return question; it does not establish that any of them earns resources while closed or syncs to a phone.

Cookie Clicker: four cookies were still there after a direct refresh.

Kittens Game: two gathered catnip remained after Save and refresh.

Antimatter Dimensions: the purchased first dimension remained after Save and refresh.

Method: on September 27, 2026, we used the linked browser versions in one browser without signing into any game account. We made one small early-game change in each game, observed its save controls, refreshed the page, and checked whether the changed state remained. The test did not clear site data, switch browsers or devices, or leave a game closed long enough to measure offline production.

Cookie Clicker: a refresh kept the cookie count

In the browser version marked 2.058, our test reached four cookies. A direct page refresh reopened at four cookies. The game's Options panel said it autosaves every 60 seconds and offered Save, Export save and Save to file. A reminder after reopening also pointed to Export save and Save to file for backups.

For a brief visit, the visible Options → Save control offers a manual precaution before stopping. Our four-cookie refresh confirms that this run returned in the same browser; we did not use that manual control, and we did not test how much the game produces with the tab closed.

Kittens Game: a manual save survived the refresh

On the linked web version, the header showed a Save control and a Saved! message. We clicked Gather catnip twice, saw the resource panel reach two catnip, clicked Save, and refreshed. The resource panel still showed two catnip. The Options panel also exposed Export and Import controls. The page identified this run as version 1.6.1.6.r163.

That is evidence of a retained early state, not a promise of quick advancement. In a player discussion of Kittens Game, one player described slow progress even after a week on mobile, while others said the slow pace was part of the game. Those are player experiences on a different platform and stage, not results of our two-catnip browser test.

Antimatter Dimensions: the first purchase survived

The linked browser game opened with ten antimatter and no production. We bought one first Antimatter Dimension for ten antimatter; the display changed to one antimatter per second. In Options → Saving, we saw a Save game button and an autosave interval of 30 seconds. We saved, refreshed, and found the first dimension still owned. The saved game also continued to display one antimatter per second.

The same Saving panel said Google login enables Cloud Saving, while this test was not logged in. We did not test cloud saves. The visible local return is the supported finding, not cross-device transfer.

Does saving mean offline progress?

No. Our test verified that a small saved state returned after refreshing in the same browser; it did not measure resources earned during a long closure. Players in a discussion of offline progress disagreed about how much offline earning matters in short versus long games. That debate is about a different question from whether a save survives a reload.

Nor is a local refresh proof against browser-data loss. A player reported losing years of Cookie Clicker progress after clearing browser data. We did not repeat that destructive action. If a long-running save matters to you, use the export or file-backup controls you can see in the game before treating the browser copy as your only copy.
